Abstract: A light source driving device includes: a light emission control unit configured to control light emission of a light source in response to an instruction signal; a communication circuit which receives a first instruction signal instructing first light emission control for visible light communication; and a timer which starts to measure waiting time for executing the first light emission control, triggered by the reception of the first instruction signal. The light control unit starts the first light emission control of the light source in response to an instruction signal at the end timing of the waiting time.
